REINFORCED-CONCRETE RAILWAYTIE Specicationof Letters Patent.

Tatent'ed Nov. 2G, MM2@ Application filed .,Tuly 22. 1911. Serial No. 639,938.

l` alt whom 'it 'muy concern:

lle it. k-nown that l, BYRON lV. liNNicY, a citizen of the United States. residing' at Lestershire, in the county of Broome andibtate ot' New York, have invented new and useful lmproveinentsl in Reint )i'eeclConc1ete Railwaylfies, of which the following is a speciieat'ion.

rl`his invention provides an indestructible cross-tie for use in the construction yof railways,said tie ha vineits body portion formed of concrete and reinforced7 said reinforcement being' utilized as anchoring,r meansl for the rail chairs, the latter being suppliefjl with cushioning' seats for relieving the rolling stoel; of excessive vibration,

The invention contemplates novel meansl for securing the rails to the tie'. said means also serving as fastening meansl between the Ar further purpose of the invention is the provision of eliprA which are adapted to interlock with the rail chaire, thereby preventing turning 'ot the clips upon the fastening so that a single securing element may be successfully aud advantageouslv employed.

The invention consists of the novel fea,- tures. details otl construction and combination of parts, which hereinafter ill be more particularly forth, illufttaieu in the aeeompan'viugrr drawinggfs7 and pointed out in the appended claims. 1

Referring' to the dra wings, forming a part of the specitieation, Figure l. is a side vienv of a concretercross` tie Vfor railways embottfine' the invent'mn` parts being brot-:en away to show more clearlyY the relative arrangementA of the reinforcement and the chair. Fie'. is a top plan view of an end portion of the tie. the dotted lines showing the posi-- tion of the rail. Fig. 3 is a section on the line ,rvr-m ot' Fic'. Fig. =t is u section on the line f/ of l 'M'. Fig. 5 is a perspective view ot' the rail chair. ltigj. t3 is a perpiw-ltive vieu,Y of one of the clip-sAh t'"orresptinline and lilie paris are referred to in the following deseripion. and indY `att in all the view-1 et' the dra'ri'ings, by' ila, same reference characters.

r:"he tie embodiesI a .body portion t which is, formed ot concrete. the saine being' molded in any convenient way. A beam Qt is embedded iu the concrete forming the body olf the tie. and extends4 to within a short distance otl eaeh end thereof, 'l`he reinforcing beam is substantially of 1li-forni in cross section,

ilthongh it may be of any cross sectional vshape. Openings are formed in the beam at; intervals in its length to admit of the concrete or plastic material forming bonds. A rail chair 3 is located near each end of thetie and is secured to the reinforcing beam Q which serves a firm anchorage therefor. The rail chair niaiv7 be cast or formed in any manner and has a recess l in its under side to receive the upper portion of thereinf0rcing' beam, the portions of the chair at the sides of theV recess embracing opposite sides of the beam. Q to prevent interni displacement of the chair. .l recess is formed in the upper side of the chair and extends at a right angle to the recess t .in the under side of the chair. cushioning' plate 6 is fitted in the recess 5 and rn'eferably consists of a block ot' wood which is adapted to neutralize in a measure the vibration, thereby prevent ing' excessive wear upon the rolling stock. 'l'he end pei-tions ofthe rail Chair upon opposite sides of the seat 5 have openings 0r reeesses 'i' designed to receive tanges 8 of clips il. thereby preventiincr movement', of said clips after the saine have been placed in proper position and made secure by the fastening means. The rail ehairs are placed direetlv upon opposite end portions of the reinforcingheani L) and are secured thereto by the saine tastenin} 4 means which hold the eushioningf seats o and the clips in place. yt`he rai! chain: are embedded in the concrete or plastic material from which he tie is rmetl o a depth to admit of the upper snrfaee of the cushioning' seats C and the enel portionsl of the rail chairs ha A-j the re eesses 't eomin;r about flush with the upper side of the tie. The fasteningy means for the rail chairsl consist. of bolts 10 which pass through registering' openings formed in enel portions of the beam the rail chairs` the cushioning; seata and the clips. the projeetine* ends, receiving' mi whereby thepars are drawn together, thereby serving' to holel the rail "l allgune'ive v rts in firm pos-iti ai. the operai 'formed in the enst c' ,if-'aniuniform distance LT y serve es n'teans fr.; prop* erlv gagne the track when eonstriu-tjingr the lsame. rihe rail eliairs a re secured to the reinforcing benin il prior to molding' the concrete or other plastic material about the saine to t'orm the composite tie. v 'lhe elips 5l may tie east, forged, or ronstructed in any manner and are substan loo Q v 'i 1,045,741

tially of L form in edge vievthe main portion of the clip adapted to extend over the tie with its inner end loverlapping the foot' of the rail and the .pendent flange 8 entering lthe opening Aor recess Each bolt passes through an opening of'the clip, the latter being prevented from turning by reason of the ange 8 entering the opening 7. By removing the nuts ll the clips may be displaced, thereby admitting of removal of the rail. v

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to Which the invention appertains, and While have described the principle o f operationcf the invention, together with the device which I now consider to be the embodiment thereof, I desire to have it understood that the device sliownis merely illustrative, and that such changes may be made When desired as are within the scope of the claims appended hereto.

A brace 12 is arranged beneath the beam 2 and is clamped thereto at its ends by means of the bolts 10. The middle portion of the brace is deflected downwardly and being embedded in the concrete forms a truss. The inner or lower ends of the bolts i0 are threaded into openings formed in the brace 12, as shown most clearly in Fig. 3.

Having thus described the invention what is claimed as netv, is

1. A railway tie comprising' a b'ody of concrete, a reinforcing beam embedded in lthe body of the tie, rail chairs embedded y in the tie and mounted upon end portions of the reinforcingbeam, each rail chair having portions embracing opposite sides of the reinforcing beam and having a depression in its top side, a cushioning iete tit-ted in the depression in the top sil e ef the rail chair, clips having their outer ends interlocking with end portions of the rail chairs and having tlieir'inner ends engaging over the foot Vof the rail, and fastenings passing through registering openings formed in theclips, cushioning plates, rail y chairs and reinforcing beam.

2. A railway tie comprising a body of concrete, a channel beam embedded in the tie, rail chairs mounted upon end portions of the reinforcing beam and having side portions embracing opposite sides of said beam, each rail chair having a depression in its top side and elongated openings in its end portions at the sides of the depression, cushioning plates mounted in the depressions of'the rail chairs, clips having pendent flanges at their outer ends to enter the elongated openings of the rail chairs and having their inner ends adapted to engage over the foot of the rails; a brace of substantially truss form embedded in the tie with its end portions in contact with the before mentioned reinforcing beam, and bolts having their inner ends threaded into the said brace and passing through registering openings formed in the reinforcing y beam, rail chairs, cushioning plates and clips and having nuts threaded upon their outer ends.

In testimony whereof I affix my signature GEO. A. RnYNoLDs, B. K. SCUDDER.
